Large inverted triangle supporting mast

Large inverted triangle supporting mast greatly increases the stability of construction and improves the

vertical accuracy of drilling.

Chassis

The chassis adopts H-type retractable track structure.It can not only ensure construction stability but also

facilitate transportation.

Power head

The power head adopts dual variable hydraulic motor and double reducer design,ensure the strong drilling

torque of power head while allowing the drilling speed and torque of power head to adjust automatically according

to geological conditions,which achieves the high-speed small torque and lows-peed high torque output of power head, in order to adapt to different geological conditions and improve

working efficiency.

Winch

The main winch adopt the most advanced winding drums with broken line grooves and the special

rope presser,to reduce chaos,skipping and mutual extrusion of rope,and wire rope is arranged in

neat order to extend its service life.

Hydraulic system

Negative flow control technology and priority control technology ensure full display of equipment

performance as well as reduce energy consumption and operator's labor intensity,and fully embody

the integration of man,machine, hydraulics and electricity.

Engine

Adopt imported Cummins turbo charger engine with such features as big power,low fuel consumption

and low noise.

Cab

The cab is safe and comfortable,easy to operate.

Electrical control system

The control system base on CAN Bus technology and PLC controller effectively realize the human-computer interaction and make operation easy.

Drill pipe and drill tool

Different forms of drills are selected under different geological conditions,to ensure the

smooth and efficient construction of equipment.
